NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Batters Patent No. 715,877, dated December 16, 1902 Application filed November 13} 1901. Serial No. 82,099. (No model.) I

To ctZZ whom it may concern.-

Be it known that I, ELMEa P. SAW'IELLE, a citizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Non-Refillable Bottles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representinglike parts.

This invention relates to a bottle or like receptacle, and has for its object to provide one which cannot be refilled. For this purpose I employ a light and a heavy ball and a coneshaped spiral having its convolutions sepa rated to form lateral passages for the liquid contents of the bottle, but which overlap one another, so as to effectively close the bottle against the passage into the bottle of a fine wire or other device, and which is provided with a top piece or disk covering the opening at the apex of the cone for the same purpose. The light ball constitutes a valve and cooperates with a conical seat, which may be formed in the neck of the bottle. Theheavy ball forms a weight which cooperates with the valve to seat the same, as will be described. The conical spiral may be made of glass or other suitable material and may be secured in the neck of the bottle against with- These and other features of this invention will be pointed out in the claims at the endof this specification.

Figure l is an elevation and section of a sufficient portion of a bottle embodying this invention to enable it to be understood; and Figs. 2 and 3, details to be referred to, Fig. 3 being an inverted View of Fig. 2.

The bottle a, provided with the neck b, may be of any suitable construction or configuration and is herein shown as provided with a contracted portion in the-neck b to form a conical port or opening 0, with which cooperates a light ball (1, of cork or other suitable material, which in practice constitutes a valve for the bottle. The cork ball (1 has cooperating with it a heavy ball 6, of glass or other suitable material, which serves to keep the ball d to its seat when the bottle occupies an upright or an inclined position.

Within the neck I) of the bottle and beyond the port or opening 0 a suitable distance is located a conical spiral f, which I prefer to designate as an obstructer, inasmuch as its function is to prevent the balls passing out of the neck when the bottle is inverted or tipped in the act of pouring and also and more particularly to prevent the passage of a fine Wire or other device into the bottle so as to reach the valve or to be inserted into the valve-opening when the bottle is in its inclined or inverted position. The conical spiral obstructer,while effectively preventing the entrance of an extraneous solid body into the bottle, does not ofier any material obstruction to the passage of the liquid out of the bottle, inasmuch as its convolutions are separated a sufficient distance to form lateral ports or passages g, through which the liquor or other fluid in the bottle may pass when it is desired to pour the same out of the bottle. The conical spiral obstructer may be made of glass or other suit able material and may and preferably will have its convolutions of suitable width to overlap one another, as represented by dotted lines, Figs. 2 and 3, and the bottom of the said obstructer may have attached toitcrossbars h, which prevent the ball e from closing the opening in the bottom of the obstructer when the bottle is tipped in the act of pouring. The conical spiral obstructer is provided with a top piece or disk k, which covers the opening at the apex of the cone and prevents the insertion of a fine wire down through the center of the cone. ter may be secured in the neck of the bottle against removal without destroying the same in any suitable manneras, for instance, by means of a bead 41, formed in the neck of the bottle after the obstructer is placed in position, which bead is indicated by dotted lines, Fig. 1, or by means of a suitable cement or in any other suitable manner.

I may prefer to employ the conical spiral obstructer with a ball-valve and with a ballshaped weight; but I do not desire to limit my invention in this respect, as it is evident the said obstructer may be used with other forms of valves and weights cooperating therewith.

I claim- 1. The combination with abottle or like receptacle, of a valve to close said bottle, and.

The obstruca conical spiral obstructer located in the neck of the bottle and having its convolutions separated to form lateral passages and provided with a top piece or disk integral with said convolutions and covering the opening at the apex of the cone, substantially as described.

2. The combination with a bottle or like receptacle, of a valve to close said bottle, and a conical spiral obstructer located in the neck of the bottle and having its convolutions overlapping one another and separated to form lateral passages and provided with a top piece or disk attached to the convolutions and covering the opening at the apex of the cone, substantially as described.

3. The combination with abottle or like receptacle, of a light ball located in the neck ELMER P. SAWTELLE.
